EAST LANSING — St. Ignace had three state championship trophies back in the Upper Peninsula before the start of Saturday’s Class D title game, but never an unbeaten season.

The Saints used a dominant fourth quarter to cross that off the list.

Emily Hinsman scored 20 points and St. Ignace outscored Waterford Our Lady of the Lakes 21-6 in the final period for a 59-44 victory and the school's second crown in three years.

The Saints (27-0) scored 30 points off the Lakers' 27 turnovers and scored the first nine points of the final quarter to break a 38-all tie and take the lead for good.

“We were able to get into passing lanes, cause deflections and get more turnovers,” St. Ignace coach Dorene Ingalls said. “Everything fell into place from there.”

Our Lady of the Lakes (21-5) coughed up the ball 15 times in the first half but led 28-23 at intermission after making five of its nine tries from behind the arc. The Saints struggled to get good looks in the first half and turned to their defense.

“Picking up our intensity on defense led to our offense,” said Sarah Cullip, who had four of her 16 points during the decisive run and grabbed nine rebounds.

Lexie Robak scored 25 points, including six 3-pointers for Waterford. Jessica Parry added 10 for the Lakers, who were seeking to become just the second girls' team in state history to win four straight titles.

“Once we got behind, they’re so good at taking care of the ball,” coach Steve Robak said. “That’s the style they like to play, and we weren’t patient with the ball.”

Flint Northern, from 1978-81 in Class A, is the only school in MHSAA history to win four straight girls basketball finals championships.

Our Lady of the Lakes further stymied itself by going 2-for-12 in the final period.

Kelley Wright added 10 points and five assists for St. Ignace, which won its first Class D title after winning the first three in Class C.

"Any time you win one, it feels like the first," said Ingalls, the coach for all four titles over the last 14 seasons.

The Saints were ranked No. 1 in the Associated Press poll from start to finish this season. The Saints ended their seven-game postseason run with an average margin of victory of 23 points.
